The proprietary driver (570.133.07) did manage to light up the external monitor over USB-C/DP. It was utterly unusable, as I couldn't make it do 100% scaling on the external screen and 200% on the high-DPI laptop screen, and my attempts to do so (just using the GNOME control panel) ended up with weird effects and wrong scaling and the mouse pointer not really taking effect in the place I thought it was pointing... but setting that aside, yes.

The display *did* light up.I don't know anything about capabilities of our driver w.r.t. scaling, but what happens if you try to keep everything at 100%? It's possible what you're trying to do is just not supported by GNOME, Wayland, Xorg, and/or our driver.> > If the proprietary driver works just fine, then we know that it's a > > bug/limitation in how Nouveau talks to GSP-RM.?

If the proprietary driver doesn't work, then there's no hope for Nouveau working. ?That's because the GSP-RM firmware that Nouveau depends on *is* the Nvidia proprietary driver. I hate to say this, but you're going to have to work with your laptop vendor and/or Nvidia support to get the proprietary driver working first.
